Students’ Critical Thinking Skills in Learning Science at Subject Structure and Function of Plant Networks using The Project-Based Learning Model in Class VIII MTs Muhammadiyah 02 Pekanbaru

Abstract

This study aimed to see how students' critical thinking skills were applied after the Project-Based Learning model was applied. This research is experimental research with Two-Group Pretest-Posttest Design. The population of this research was of 216 students. The sampling technique used was a simple random sampling technique, 36 students for the experimental class and 36 for the control class. The instrument used is a test. The hypothesis testing using a t-test found that the tcount was higher than ttable (2,399>1,688). From the results of the analysis, it was found that there were significant differences in students' critical thinking skills with the Project-Based Learning model compared to the conventional model.
